Lately I have been trying new stuff with my inks and I feel like most of my brushes can be classified in one of two categories that I switch between from picture to picture.
As I call them Flat
and textured
Each has their merits and their flaws, and while most people I know use flats, the best ones swear by textured.

So what do you think?
What tools do you use to ink your pieces and how do you use them?

To start, I think that opinion of "the best ones" is a bit excessive. There are plenty of amazing and well known artists that use a flat inking brush as opposed to a textured one. Just wanted to throw that out there.

I think honestly the different uses of different kinds of inking brushes mostly come from how you were taught to draw. If you started with pencil and paper, you're probably going to lean more toward textured brushes.
It also depends on what kind of style or subject you're drawing; If you're using a lot of textures, the use of a flat inking brush might look off.

I for one, used to use a thick textured brush but have recently moved to a thin flat inking brush.
